I'm a 20 year old guy, about 6 foot 3 tall, and I have always been very skinny. I always ate a reasonable amount, but never gained hardly any fat or weight.
I'm in the 2nd year of uni, and eat a lot there. On an average week I cook for myself 4 days (quite large portions), get fish & chips from the chippy one day, get a Dominoes pizza one day, and have a pub roast beef after church on a Sunday.
I go to the gym 2 to 3 times a week both at uni and at home, and at home I frequently go on long country walks. But currently at home for Easter, I am increasingly horrified at the big belly I seem to be acquiring.
What should I do?!
